"Microsoft launched ASP.NET MVC 1.0 at the MIX09 event last month. This new ASP.NET enhancement brings a Rails-like model-view-controller framework to Microsoft's Web development stack. In a blog entry published on Wednesday, Microsoft developer division vice president Scott Guthrie announced that the framework is now open source. The source code is available under the terms of the Microsoft Public License (MS-PL), a permissive open source software license that has been approved by OSI and is characterized by GNU as a free software license. Microsoft's move to open the framework will enable third-party developers to modify the source code, incorporate it into their own software, and share it with other users."
